On July 30, Lam Research rose 7.89% in pre-market trading, trading at $266.01/share, with turnover of $1.5811 million. The surge follows the company's after-hours earnings release the prior session, which delivered record results and guidance far exceeding Wall Street expectations.

Lam Research reported fiscal Q4 adjusted EPS of $1.82, beating the consensus estimate of $1.68-$1.69 by approximately 8.3%, representing a 36.8% year-over-year increase. Revenue reached $6.722 billion versus expectations of $6.665 billion, both marking all-time highs. Gross margin expanded from 49.8% to 51.7%, while operating margin rose from 35.0% to 37.4%. CEO Tim Archer attributed the performance to AI-driven demand reshaping the semiconductor industry.

More critically, Q1 guidance significantly surpassed expectations, with projected revenue of $7.70 billion to $8.50 billion versus the analyst consensus of $7.11 billion, and EPS guidance of $2.00 to $2.30 versus the expected $1.84. The stock had previously declined from approximately $306 on July 27 amid memory stock weakness and pre-earnings uncertainty, and the strong results eliminated the overhang, triggering a sharp technical rebound.
